Question

find the factors of the polynomial given below. y²+17y-70​

Answer 1

Step-by-step explanation:

I think there is mistake ....there must be +70 instead -70

then it can solve by splitting middle terms

then answer be (y+10)(y+7)...

thank you .....

Answer 2

Answer:

${y}^{2} + 17 - 70 \\ y {}^{2} + 17 - 70 = 0 \\ {y}^{2} + 10y - 7y - 70 = 0 \\ y(y + 10y) - 7(y + 10y) = 0 \\ y - 7 = 0 \\ y + 10 = 0 \\ then \: y = 7 \: and \: - 10| \\ so \: 7 \: and - 10 \: is \: factor \: of \: the \: equation$
